Specification of Letters Patent.

To @ZZ who/r1.l t nfl/(ty con/cern:

Be it known that we, GRLANDO J. Sn'FfroN and CHARLES A. SnFToN, ofWichita, in the county of Sedgwick and State of Kansas, have inventedcertain new and useful Improvements in Cultivators; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in cultivators, and is of thatclass which uses disks instead of shovels and is especially ad apted tocultivate large corn as well as small listed corn.

Heretofore cultivators adapted to small listed corn did not work well insecond and third plowing.

The improvement consists of the novel features and the peculiarconstruction and combination of parts, which will be hereinafter morefully described and claimed and which are shown in the annexed drawings,in which-- Figure 1 is a side elevation of our cultivater, one of therear wheels being removed. Fig. 2 is a plan View of the machine withportions broken away to more fully illustrate; Fig. 3, side view offront truck-wheel, showing the method of attaching` the axle thereto;Fig. 4, rear view of front truck-wheel, showing the adjustment of thesaid axle; Fig. 5, a front view of the front truck; Fig. 6, a rear Viewof the rear truck; Fig. 7, the arm connecting the disk to thecultivator; Fig'. 8, a section of a square shaft transversely positionedin the frame of the machine; Fig. 9, an end view of the journal. on thesquare shaft 8.

Similar figures indicate corresponding parts throughout.

1 indicates a pair of iron bars bent and arched as seen in Fig. 1, thefront ends thereof being higher than the body portion and riveted to arectangular plate of iron 7.

5 is an arched frame, Fig. 4, preferably made of iron, the free endsthereof having' adjustably affixed thereto by bolt 50 axles 49, saidaxles being of the form shown and are provided with collars 60, whichare secured on said axles by set screw 52. Wheels 6 are placed on saidaxles, a washer 53, placed next to said wheel, and linchpins 54 to holdthe wheel thereon. A disk 10, having a round opening in the centerthereof, is positioned on the top of the arched truck-frame 5, whichframe has an opening 61 therein. An A-shaped brace 11 is provided, thefree end thereof being secured to the frame by rivets 12 and the topportion of the brace having a hole therein to receive the bolt 13. Oneither side of the frame 5, Fig. 1, are braces 8, their free ends beingsecurely riveted to the disk 10, the central portion of said bracehaving' round openings to receive pivots 12, Fig. 1, which secure thebraces to the axle 5. A tongue 18 has afHxed thereto rods 14 by bolts15, the free ends having openings to receive the pivots 12, which allowsthe free end of the tongue 18 to swing up and down, which is animportant feature in crossing over ditches and ridges. Spiral springs 16are attached to the tongue 18 by means of eyebolts 17, which are screwedinto the tongue, the other ends of said springs being pivotally attachedto the frame 5. It will be seen said springs will allow the tongue 18 tomove freely up and down and also help support the frame 5 in crossingover an obstruction.

A rear axle 3, Fig. 6, of the form shown is provided with collars 55,held in the proper position with set-screws 56. Vheels 4 are kept on theaxle with pins 57. Bars of iron 1, bent and arched in the form shown inFig. 1, are spaced parallel about twelve inches apart. The front endsare securely riveted to a rectangular plate of iron 7, having a hole inthe center thereof which is to receive the pin 13. It will be seen thisplate 7 and the disk 10 constitute a fifth wheel, which will allow thefront wheels of our plow to turn in any direction. An evener 29 isplaced on top of the rectangular plate 7, through which the pin 18passes, the top end of the pin 13 having a supporting-brace 30 extendingback and down and secured to the rear side of plate 7. Therearends ofthe bars 1 have upward bends 27 and are slidably attached to the rearaxle by means of U-shaped bolts 28, having nuts thereon. Said bolts arepassed over the axle and through holes in the bars 1, by which means theaxle and the bars can be adjustably clamped together and the entire rearportion of the machine can be raised and lowered on the rear axle.Auxiliary bars 2 are bent in the form shown in Fig. 2 and are rigidlyattached to bars 1 by means of rivets 62, the other ends thereof beingadjustably attached to the rear axle by means of U-bolts 34. Rockshafts19, having on either end thereof journals 21, are transversely pivotedbetween bars 1 and 2, Fig. 2. On the rear bars are vertical standards47. Thelower ends of said standards are provided with quadrangularopenings therein to receive the squared portion of the rock-shaft 19,the other ends having round openings therein. Levers 38 have their lowerends attached to the front rock-shafts 19, the same as standard 47, saidlevers having thumblatches 40 pivotally secured thereto by rivets 39.Pendent from said latches are rods 42, passing through loops 43. Aspiral spring 41 is positioned between lever 38 and thumblatch 40, whichwill insure the pendent-rods 42 engagement with the segmental racks 44,said racks being attached to bars 46. One end of each of said bars ispivotally connected to a lever 38 with rivet 45, the other end to avertical standard 47 with rivet 48. Clamps 25 are afiixed to the squarebars 19 by the usual means-in the present instance by a parted boxhaving a square transverse recess in the lower half to receive bars 19and a longitudinal round opening in the top half to receive the ends ofthe rods 23, said boxes being clamped together with bolts 24, by whichmeans the box can be transversely adjusted on the shaft 19 to anyposition desired. rIhe rear end of the shafts are ad justably clampedbetween parted boxes 24, Fig. 2, the lower portion of each of theseboxes having a round opening therein, in which is placed a round pintle63, which makes an axle for the disks 22. It will be seen the arches 26in bars 1, Fig. l, will permit the disks 22 to move laterally underbars 1. To the top edges of the arches 26 are secured by the cap-screws36 the ends of 'spring-bars 35, which ends 61 are bent laterally for thepurpose of making a foot-rest for the driver, as clearly illustrated inFig. 2, these springs 35 extending up and rearwardly, having positionedthereon a seat 37. When cultivating listed corn the first time, it isessential the two front wheels of the cultivator run in the ditch. Thisis largely accomplished by an adjustment of the two front wheels, asindicated by the dotted lines, Fig. 4, which angle keeps the said wheelsfrom climbing up the banks and leaving the ditch should the horses notstraddle the row properly. When the ditches are well filled up and thecorn is being layed by, the wheels can be straightened up by means ofthe adjustment of the axle as shown inV Fig. 3. A sled 31, whose runnersare of sheet-iron and have affixed to the front end rods 32, said rodshaving lateral bends on their free ends, which pass through roundopenings 64 in the vertical parts of the bars 1, is provided. A chain 33is attached to the rear end of the sled and is carried up and afxed tothe top of the arch of the axle 3.

Having thus explained the details of construction of our cultivator, wewill now proceed to describe its operations generally. Then the operatordesires to force the disks into the ground, he pulls the lever 38 back,which lever being' rigidly affixed to the squared portion of the bars 19throws the disks 22 down, as indicated by the dotted lilies, Fig. 1. Thesaid disks can be reversed to throw the dirt either to or from the corn.rIhe sled 31 can be suspended bythe chain 33 to any height desired,allowing a portion of the loose dirt to roll in under the loweredges,and thus protecting the small corn from large clods, as hereinbeforeexplained.

It is obvious that the invention herein set forth is susceptible to manychanges and modifications involving mechanical skill which may be madewithin the scope of the invention without departing from the spiritthereof. We do not, therefore, desire to be understood as limitingourselves to the precise construction of the parts shown in thedrawings.

Having thus described our invention, what we claim, and wish to secureby Letters Patent, is-

1. In a cultivator of the character described, a rectangular plate 7, apair of arched bars 1, their front ends rigidly affixed to therectangular plate, in combination with a pivoted truck V5, havingadjustable wheels, and a tongue pivotallyv secured to said truck, spiralsprings connecting said tongue and truck, substantially as described.
